git-author-history-fix

Small Shell script to automate the revision of author info in a repository’s commit history via command line. The steps were taken from GitHub’s help page.

1. Modify history.sh script with proper email information

Change OLD_EMAIL, CORRECT_NAME and CORRECT_EMAIL to the correct values

git filter-branch --env-filter '
OLD_EMAIL="bademail@example.com"
CORRECT_NAME="Eric"
CORRECT_EMAIL="goodemail@example.com"
if [ "$GIT_COMMITTER_EMAIL" = "$OLD_EMAIL" ]
then
export GIT_COMMITTER_NAME="$CORRECT_NAME"
export GIT_COMMITTER_EMAIL="$CORRECT_EMAIL"
fi
if [ "$GIT_AUTHOR_EMAIL" = "$OLD_EMAIL" ]
then
export GIT_AUTHOR_NAME="$CORRECT_NAME"
export GIT_AUTHOR_EMAIL="$CORRECT_EMAIL"
fi
' --tag-name-filter cat -- --branches --tags

2. Run the script via command line

. history.sh git@github.com:username/repository-name.git
